24 bit image problems

[Norman Barker]

Hi,

I have a WMS that is reading 32 bit data, I would like to render this as png24 to get all the colours.

An example is currently at
http://217.37.214.210/cgi-bin/mapserv.cgi?map=/tmp/portrayal/test/test.map&REQUEST=GetMap&FORMAT=png24&WIDTH=640&HEIGHT=480&SRS=EPSG:4326&BBOX=-122.242,37.3957,-122.2,37.4162&VERSION=1.1.1&LAYERS=PCA

The 24 bit mode doesn't seem to be working, any help would be appreciated.

MAP
    NAME TEST
    STATUS ON
    IMAGETYPE png24
    IMAGECOLOR 240 240 240
    SHAPEPATH "/tmp/portrayal/test"
    PROJECTION
      "init=epsg:4326"
    END
#  OUTPUTFORMAT
#    NAME png24
#    DRIVER "GD/PNG"
#    MIMETYPE "image/png"
#    IMAGEMODE RGB
#    EXTENSION "png"
#  END
    WEB
        IMAGEPATH "/var/www/html/tmp"
        IMAGEURL "/tmp/"
        METADATA
          "ows_title" "test"
          "ows_srs" "EPSG:4326"
        END
    END
    LAYER
          NAME "PCA"
          TYPE RASTER
          STATUS ON
          DATA "jsp99hym_rad_pca_geo.bil"
    END
END

Many thanks,

Norman Barker
